1. the final stage of mitosis and of the second division of meiosis in which the spindle disappears and the nucleus reforms around each set of chromosomes.
3. a protein structure that divides the genetic material in a cell
5. the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
8. the interval between the end of one mitotic or meiotic division and the beginning of another.
9. a usually round part of most cells that is enclosed in a double membrane, controls the activities of the cell
10. the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
13. that generate most of the chemical energy needed to power the cell's biochemical reactions
15. the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
